Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK POWER SOURCE (STOP LAMP SWITCH)
   
   
   1. Turn ignition switch OFF.
   2. Disconnect stop lamp switch connector.
   3. Check voltage between stop lamp switch connector E38 terminal 1 and ground.

      Stop lamp switch		Ground	Voltage (Approx.)
      Connector	Terminal
      E38	1		Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 2  .

   NO 

   Check the following:

   • Harness for short or open between fuse block (J/B) and stop lamp switch
   • 10A fuse (No. 10, located in fuse block [J/B])
2. CHECK STOP LAMP SWITCH
   
   

   Check stop lamp switch. Refer to COMPONENT INSPECTION (STOP LAMP SWITCH) (RE0F10E) or COMPONENT INSPECTION (STOP LAMP SWITCH) (RE0F10J).

   Is the inspection result normal?

   YES 

   GO TO STEP 3  .

   NO 

   Replace stop lamp switch. Refer to EXPLODED VIEW .

3. CHECK GROUND CIRCUIT (BCM)
   
   
   1. Disconnect BCM connector M81.
   2. Check continuity between BCM connector M81 terminals 134, 143 and ground.

      BCM		Ground	Continuity
      Connector	Terminal (+)
      M81	134		Yes
      	143

   Is the inspection result normal?

   YES 

   GO TO STEP 4  .

   NO 

   Repair or replace damaged parts.

4. CHECK HARNESS BETWEEN BCM AND STOP LAMP SWITCH FOR OPEN
   
   
   1. Disconnect BCM connector M18.
   2. Check continuity between BCM connector M18 terminal 27 and stop lamp switch connector E38 terminal 2.

      BCM		Stop lamp switch		Continuity
      Connector	Terminal	Connector	Terminal
      M18	27	E38	2	Yes

   Is the inspection result normal?

   YES 

   GO TO STEP 5  .

   NO 

   Repair or replace damaged parts.

5. CHECK HARNESS BETWEEN BCM AND STOP LAMP SWITCH FOR SHORT CIRCUIT
   
   

   Check continuity between BCM connector M18 terminal 27 and ground.

   BCM		Ground	Continuity
   Connector	Terminal
   M18	27		No

   Is the inspection result normal?

   YES 

   GO TO STEP 6  .

   NO 

   Repair or replace damaged parts.

6. CHECK HARNESS BETWEEN BCM AND CVT SHIFT SELECTOR FOR OPEN
   
   
   1. Disconnect CVT shift selector connector M78 and BCM connector M80.
   2. Check continuity between BCM connector M80 terminal 108 and CVT shift selector connector M78 terminal 3.

      BCM		CVT shift selector		Continuity
      Connector	Terminal	Connector	Terminal
      M80	108	M78	3	Yes

   Is the inspection result normal?

   YES 

   GO TO STEP 7  .

   NO 

   Repair or replace damaged parts.

7. CHECK HARNESS BETWEEN BCM AND CVT SHIFT SELECTOR FOR SHORT CIRCUIT
   
   

   Check continuity between BCM connector M80 terminal 108 and ground.

   BCM		Ground	Continuity
   Connector	Terminal
   M80	108		No

   Is the inspection result normal?

   YES 

   GO TO STEP 8  .

   NO 

   Repair or replace damaged parts.

8. CHECK GROUND CIRCUIT (CVT SHIFT SELECTOR)
   
   

   Check continuity between CVT shift selector connector M78 terminal 4 and ground.

   CVT shift selector		Ground	Continuity
   Connector	Terminal
   M78	4		Yes

   Is the inspection result normal?

   YES 

   Replace shift lock solenoid. Refer to EXPLODED VIEW (RE0F10E) or EXPLODED VIEW (RE0F10J).

   NO 

   Repair or replace damaged parts.
